To all 'whom 'it may concern.' y

lBe it known that l, ALEX-ANDER particularly to locks that may be used upon bothswinging and sliding doors. rlhe principal object of my invention is to provide a bolt that shall securely lock the door when shifted from the casing into a'keeper, and

I subsequently to said'locking operation to interlock said keeper with said casing.

The present invention is an improvement upon the invention disclosed in my application filed December 30, 1919. The main ob ject of this improvement is to reduce the number of parts and to simplify the construction of said lock andthus 'render' it less likely to get out of order and cheapen the manufacturing cost thereof.

Other objects and advantages will appear inthe specification given herein. n

In the accompanying drawing, Figure 1 is a sectional elevation of the lock showing the disposition of the'mechanism when in unlockedstate. Fig. 2 is a view similar to that'shown in Fig. 1, but showing the 'ar rangement of the parts of the lock when in locking and interlocking state. Fig. 1 also shows in broken lines the position of the bolt when in locking state, only prior to being` projected into vengaging position. y

The lock embodied in myv invention embraces ametal casing 1 anda keeper 2. A. bolt 4L having a hook 5 on itsouter or locking end is connected to a frame?) provided with slots 10 and 11, and projections 8c and 9. A stud 12 on casing 1 is arranged to be receivediin said slot 10, and a lever or any other suitable device may be provided for projecting the bolt into engaging position, said lever 14' being preferablyv pivoted on said casing 1 and providedfwith a stud 18 kadapted to 4be received by slot v11 on said frame 3. Y i

A 'pawl `19 ispivoted on said framea at 22, and comprises a pivot head 21, a proyjection20 bearing-'upon projection 8d of frame 3, a ledge'23 abutting'on a lug 24 on casing 1 andrajspring'25connected -at itsrv niet head 21.iflaaneasaest .Stad 26:

Said pawl 19 tends to maintain hooked bolt l in locking positionv prior to the projection of said bolt into engaging position. l

A pawl-pressed device for actuating said lever f11i, said lever actuator 27 eing movable in casing 1y and guided in its movement and guarded against displacement laterally by suitable means-not shown. Said actuator is provided with projections 28 29 and a tumbler pawl pivotally mounted thereon at 32. Said pawl embraces a pivot head 31, a projection 34 bearing on projection 28 of actuator 27, a ledge 35 abutting on a lug 36 on casing 1 and a spring attached te its pivot head 31 and leaning against a stud 33C. A link 1S is pivotally attachedby one end tosaid actuator 27 and by the other end to lever 1d through an arm 16 attached to said lever 14;, which is pivoted on casing lat 15.

An armor `a--cam 38 is mounted upon a rotatable sleeve 87, which is rotatable by means of key operated mechanism, and a separate similar device may be operated by means of a knob. Said cams are adapted to operate the locking mechanism, vmoving the hooked boltv longitudinally and subsequently projecting said bolt into engagin@` position.

To perform the complete locking operation, cam 38 upon being operated by rotate ingY sleeve 37 by said key mechanism, first releases frame 3 by bearing against projec! tion 2O of pawl 19, then said cam bears against projection Se of frame 3 and moves said bolt into locking kposition in keeper 2, said studs 12 and 13 functioning guides for said frame 8. ln completing therevolution, said cam 3S further encounters said le# ver actuator 27 and its pawl, bearing against projection 34 of said pawl and releasing said actuator, then bearing against projection 28 of said actuator moves said actuator in a c irection to operate lever 1d and cause stud 13 on said lever to swing said bolt L1*--5 on stud 12 on the casing as a pivotal point and interlock the casing withV the keeper. The Apawl on said actuator engages againwith lug 36 `on 'casing 1, and thus locks saidv actuator,
